Advisories MDKSA-2006:135: Updated freeciv packages fix DoS vulnerabilities

[paul]

Buffer overflow in Freeciv 2.1.0-beta1 and earlier, and SVN 15 Jul

2006 and earlier, allows remote attackers to cause a denial of service

(crash) and possibly execute arbitrary code via a (1) negative

chunk_length or a (2) large chunk->offset value in a

PACKET_PLAYER_ATTRIBUTE_CHUNK packet in the

generic_handle_player_attribute_chunk function in common/packets.c, and

(3) a large packet->length value in the handle_unit_orders function in

server/unithand.c.

 

The updated packages have been patched to fix this issue.
